摘要： The invention provides a new route for the synthesis of carbon-coated powders having the olivine or NASICON structure, which form promising classes of active products for the manufacture of rechargeable lithium batteries. Carbon-coating of the powder particles is necessary to achieve good performances because of the rather poor electronic conductivity of said structures. For the preparation of coated LiFePO 4 , sources of Li, Fe and phosphate are dissolved in an aqueous solution together with a polycarboxylic acid and a polyhydric alcohol. Upon water evaporation, polyesterification occurs while a mixed precipitate is formed containing Li, Fe and phosphate. The resin-encapsulated mixture is then heat treated at 700 °C in a reducing atmosphere. This results in the production of a fine powder consisting of an olivine LiFePO 4 phase, coated with conductive carbon. When this powder is used as active material in a lithium insertion-type electrode, fast charge and discharge rates are obtained at room temperature and an excellent capacity retention is observed.
摘要翻译：本发明提供了一种用于合成具有橄榄石或NASICON结构的碳涂覆粉末的新途径，其形成用于制造可再充电锂电池的有希望的活性产品类别。由于所述结构的电子导电性差，所以粉末颗粒的碳涂层是必需的，以获得良好的性能。为了制备涂覆的LiFePO 4，将Li，Fe和磷酸盐源与多元羧酸和多元醇一起溶解在水溶液中。当水蒸发时，在形成含有Li，Fe和磷酸盐的混合沉淀物的同时发生聚酯化。然后将树脂包封的混合物在还原气氛中在700℃下进行热处理。这导致由导电碳涂覆的由橄榄石LiFePO 4相组成的细粉末的生产。当这种粉末用作锂插入型电极中的活性材料时，在室温下能够获得快速的充放电率，并且观察到优异的容量保持率。

摘要： The invention concerns the manufacture and use of phosphates of transition metals as positive electrodes for secondary lithium batteries and discloses a process for the production of LiMPO 4 with controlled size and morphology, M being Fe x Co y Ni z Mn w , with O ≤ x ≤ l, 0 ≤ y ≤ 1, O ≤ w ≤ l and x + y + z + w = l. A process is disclosed for the manufacture of LiFePO 4 , comprising the steps of - providing an equimolar aqueous solution of Li 1+ , Fe 3+ and PO 4 3- , - evaporating the water from the solution, thereby producing a solid mixture, - decomposing the solid mixture at a temperature below 500 °C to form a pure homogeneous Li and Fe phosphate precursor, and - annealing the precursor at a temperature of less than 800 °C in a reducing atmosphere, thereby forming a LiFePO 4 powder. The obtained powders have a particle size of less than 1 μm, and provide superior electrochemical performances once mixed for an appropriate time with electrical conductive powder.
